Great questions, Selicos.
Unfortunatley, one 1080 Ti is not a big enough gain in render speeds for GPU rendering, for me. Faster renders is determined by CUDA counts. Also, overclocking GPU's almost does nothing to improve render times, at least not with my render engines. The 980 Ti has 2880 CUDA's, while the 1080 Ti has 3584 CUDA's. It would be faster, but not fast enough for me to replace it.
2x 980 Ti would cut my render times in half. 2x 1080 Ti's would render 3x faster than my single 980 Ti. It would be nice to have in my animation pipeline but I need the portability for my freelance work.
I went with a binned chip to make sure I can achieve good over clocks. I had a bad chip with my 4770K. I had to delid that one myself just so that it would not throttle on stock settings. Yeah, there are many Kaby Lake's that hit 5.0GHz. It is a 70-75% chance of hitting that.
I would like this feature, too. How up vote this?
Thank you joshzpants!
